Web developers building for the future in Bangkok
TrueDev is a web development company in Bangkok, building marketing sites, custom web applications and e-commerce stores for Thai businesses, hotels, property groups and international companies operating across Southeast Asia. We've been writing software since 1997, and an AI-augmented workflow now lets a compact senior team ship fast, modern web products that out-perform what a traditional Bangkok agency would deliver in the same time.
Our stack is built for speed and longevity: Next.js, React and TypeScript on the front end, Node and Supabase behind it. That means sites that load instantly, score green on Core Web Vitals, rank well on Google, and scale from a simple landing page to a full SaaS platform without a rebuild a year later.
You work directly with the engineers writing your code — no account-manager layer, no offshore handoff, no specs lost between teams. We meet in Bangkok hours, in English, Thai or Swedish, and you own 100% of the source code, design files and data from the very first commit.
Why Bangkok businesses choose TrueDev for web development
A senior team, AI-accelerated delivery, and full ownership of everything we ship.
Fast and affordable
AI-augmented development means we deliver polished, production-ready websites in weeks — at a fraction of what enterprise agencies in Bangkok quote, with zero drop in craftsmanship.
Built for Core Web Vitals
Every site we ship is tuned for speed: server rendering, optimised images and clean code that scores green on Google's Core Web Vitals and keeps visitors from bouncing.
SEO-ready from day one
Semantic markup, structured data, fast pages and multilingual support baked in — so your site is built to rank, not retrofitted for SEO after launch.
Modern, future-proof stack
Next.js, React, TypeScript and Supabase — the same tools the world's best product teams use, so your site stays maintainable for years, not months.
One team, end to end
Strategy, design, development, content and hosting handled under one roof in Bangkok — a single point of accountability from brief to launch.
You own your code
Source code, design files, domains and data are yours from the first commit. No proprietary page-builder lock-in, no hostage situations.

Websites that load instantly and rank on Google
We sweat the details most agencies skip — server rendering, optimised assets, clean semantic code and green Core Web Vitals that keep both visitors and search engines happy.

A web partner on the ground in Bangkok
Local presence, local payments and local know-how — with global engineering standards.
In your timezone
We work Bangkok hours, so you get same-day answers and real-time collaboration — not overnight email ping-pong with a distant offshore team.
Meet face to face
Based in Watthana, central Bangkok, we meet in person for workshops, design reviews and launch planning whenever it helps.
Thai payments & PDPA
We integrate PromptPay and Thai card gateways and build with Thailand's PDPA data-protection rules in mind — sites ready for the local market.
English, Thai & Swedish
Brief us in the language you're comfortable in. Our team is fluent across all three, so nothing gets lost in translation.
29 years, one city
Founded in 1997 and rooted in Bangkok, we've shipped websites here longer than most local agencies have existed.
Trusted by Thai & global brands
Real-estate groups, hospitality, fintech and international companies have launched with us — references on request.

A senior team in your timezone — not an offshore black box
Regular previews, direct access to the engineers building your site, and honest advice on what to build and what to skip. That's how we've worked since 1997.
